    This Kohler beyond repair?

    Perhaps you need to find someone with a bit of experience with Kohler engines to give you some guidance and practical help. Most engine manufacturers publish Engine Failure Analysis guides to talk one through the forensic examination of failed engines but they tend to be aimed at dealers. Found this on Amazon but it's in the US https://www.amazon.com/Kohler-Engines-Failure-Analysis-Guidebook/dp/B003M1TIVG

    This Kohler beyond repair?

    perhaps you should be asking why the rod snapped? Usual cause is lube failure of the big end but the apparent condition of the crank pin doesn't support that. Next comes over-speeding.. Any sign of governor issues and are the balancer gears correctly timed?

    Plastic Petrol Tank leak.

    If you are considering the "glue" route, I'm not sure about JB Weld but I would suggest Q Bond or the slightly oddly named Quicksteel Plastic Repair.

    Plastic Petrol Tank leak.

    If it’s a raised seam you may be able to fuse the leaking area with a soldering iron.

    hayter osprey

    The two clutch linings should be bonded to the steel centre plate. When damp gets between the linings and the centre plate it rusts and breaks the bond . When we were servicing and repairing Hayter 21s and Ospreys on a regular basis we used Loctite Multibond to glue the linings back on, quite expensive but reliable. There may be other suitable adhesives available now. Some of the worm gear boxes were serviceable with an oil level plug while others were “sealed for life” . The recommended lubricant is an SAE 90 gear oil. Note, a plain gear oil and not an EP grade, extream pressure, oil designed for Hypoid gears which can be detrimental to “yellow metal” worm gears.

    hayter osprey

    As pointed out by Fix'em all the Osprey does have a fibre clutch plate that may contain asbestos and this can absorb moisture and rust to either of the pressure plates - one of which is part of the left hand wheel hub and the other keyed to the axle. Jack the machine up , remove the split pin from the nut in the left hand wheel centre and undo the nut . At this point the wheel and hub should pull off the axle . If it wont come off, try hitting the inflated tyre with a mallet. If that doesn't work, get back to us. This may be useful. https://www.dropbox.com/s/e2rmk54zl2msh1k/Hayter Osprey and 21 0001.pdf?dl=0 https://www.dropbox.com/s/5sjvlcenhz6ghfe/Hayter 21 %26 Osprey Gearboxes0001.pdf?dl=0 https://www.dropbox.com/s/0puak77v28dnjpl/Hayter 21 %26 Osprey clutch adj20001.pdf?dl=0

    You can never have enough sheds...

    Nice shed but it depends how you rate the security risk but it looks as though the door hardware is just screwed on. Not easy to see but are those hinges and the bolt secure? One coach bolt through each side of each hinge in place of a screw and similar for each side of the bolt . Long enough to go right through with decent washers and nuts on the inside. Ideally a bolt and padlock top and bottom.

    Multiplying Mowett Mustangs !!

    That’s interesting, looks as though they concentrated on garden centres etc rather than the established mower trade.

    If a metric equivalent is acceptable https://www.bearingsrus.co.uk/gm8x01-25-dunlop?gclid=CjwKCAjwu5veBRBBEiwAFTqDwZ6pO8ixZLFvUt5BZqT7_5idAToPRJ8MFv6gXIkZBDgjEvkhYr4r_hoCp2QQAvD_BwE Also worth looking at OEM parts lists . For example, Countax use them on their grass collectors.

    Multiplying Mowett Mustangs !!

    Who were the UK importers / distributors for the Mowett and what would be the time frame when they were being bought for regular use? Other than on the front cover of a US generic garden machinery repair manual I never saw on in all my time as a dealer.

    Early Westwood Mower Wanted

    I see that there's a Westwood Clipper on that auction site at present. I'd totally forgotten that they made such a thing!.

    Early Westwood Mower Wanted

    Not that it affects the availability but the early "Westwoods" were imported and rebadged Dynamarks.

    Kohler 12 hp

    That's a configuration often used in heavier duty garden tractors such as JD, Ariens or Cub Cadet with a U/J off the back of the engine to shaft drive to the transmission and the drive to the deck via the electric clutch and one or two belts dropping down to a mule shaft under the chassis and a U/J and short shaft to the deck.. However the position of the fuel tank looks a bit wrong for that application.
  14. To be strictly accurate the Beast did not have a Merlin engine but a Meteor which was the detuned version used in armoured vehicles.

    What was the earliest British Ride On?

    But its not a chain driven fan, just happens to be on the crankshaft that's driving something else. Similar arrangement that used on several old mowers such as Atco Standards.
